INTRODUCTION

 

Hibox C2 is our second generation of a compact shifting system designed to enhance the functionality of Pinion C-line gearboxes, especially for riders using brake and shift levers on race handlebars or trigger shifters on MTB handlebars. It replaces the standard twist shifter, offering a clean and ergonomic solution for a more streamlined cockpit.

    INSTALATION

 

 

1) OPEN THE LID:

 

  • Use a screwdriver to gently pry open the lid. Be careful not to cause any damage

     

     

     

     

    2) REMOVAL OF THE OLD CONTROL UNIT:

 

  • Loosen the three screws using a 2.5mm hex key (2.5mm Allen wrench). Carefully remove the old control unit.

     

     

     

     

     

     

     

    3) SPREAD THE GREASE AND ATTACH THE HOUSING:

 

    • Use a small brush or your finger to evenly spread the grease from the pinion across the gearbox. Ensure all moving parts are well-coated for smooth operation.

    • Loosely secure the housing (1) to the pinion gearbox using the housing screws (8). Once aligned, tighten the housing screws by hand until secure.
